Abstract
The invention relates to a metal material alloy and a preparation method thereof, and particularly relates to a corrosion-resistant magnesium alloy and a preparation method thereof. The corrosion-resistant magnesium alloy consists of the following components in percentage by weight: 3-9% of zinc, 2-5% of aluminum, 1-6% of tin, 0.5-1% of manganese, 0.05-0.5% of antimony and the balance of magnesium. The hardness and the corrosion resistance of the alloy material are strengthened by fully utilizing the function of antimony and tin, and are greatly improved by selecting different metal elements and adjusting the content of different components.
Description
Technical field
The present invention relates to a kind of metallic material alloy and preparation method thereof, particularly a kind of have corrosion-resistant magnesium alloy and preparation method thereof.
Background technology
Magnesium alloy is to add other elementary composition alloys take magnesium as base.Be characterized in: density little (about the 1.8g/cm3 magnesium alloy), specific tenacity is high, and Young's modulus is large, good heat dissipation, shock absorbing is good, and the loading capacity that withstands shocks is larger than aluminium alloy, and the corrosive nature of anti-organism and alkali is good.Main alloy element has aluminium, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium etc.What use was the widest at present is magnalium, secondly is magnesium-manganese alloy and magnesium zinc zirconium alloy.Be mainly used in the industrial sectors such as Aeronautics and Astronautics, transportation, chemical industry, rocket.Be the lightest metal in practical metal, the proportion of magnesium approximately is 2/3 of aluminium, is 1/4 of iron.It is the lightest metal in the practical metal, high strength, high rigidity.
Magnesium alloy has various advantage, but for existing magnesium alloy materials on the market, can not satisfy some particular requirement, such as the very requirement of corrosion resistant material.This satisfies this demand so that need to seek different combination of components.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of corrosion-resistant magnesium alloy that has and preparation method thereof.
Content of the present invention is, formed by following weight percent component, and the zinc of 3-9%, the aluminium of 2-5%, the tin of 1-6%, the manganese of 0.5-1%, the antimony of 0.05-0.5%, all the other are magnesium.
Preferably, described zinc is industrial-purity zinc, and described aluminium is commercial-purity aluminium, and described tin is industrial pure tin, and described antimony is industrial star antimony, and described magnesium is pure magnesium.
Preferably, the present invention is comprised of following weight percent component, 6% zinc, 3% aluminium, 2% tin, 0.7% manganese, 0.4% antimony, 87.9% magnesium.
Preparation method of the present invention is, under the effect of rare gas element, the zinc of magnesium, 3-9% and the aluminium of 2-5% are joined in the smelting furnace, under 660-720 ℃ of condition, melt, then be that 0.2-0.4MPa, temperature are under the 690-750 ℃ of condition at pressure, the tin that adds 1-6%, manganese-magnesium alloy, the antimony of 0.05-0.5%, mix, heated 10-30 minute, and left standstill, cool off to get described corrosion-resistant magnesium alloy.
Preferably, described rare gas element is nitrogen
The invention has the beneficial effects as follows, the present invention takes full advantage of the ability that is used for reaching reinforced alloys material hardness and corrosion resistance of antimony and tin element, by selecting the content of different metallic elements and allotment different components, its hardness and corrosion resistance improve greatly.
